(Cl. 57-162) This invention relates to an improvement in a of Chondrus ocellatus, the mucus of Hibiscus method of manufacturing coveredwires, which am' oi root, .or he like diss l e therein, is simple, efiicient and less expensive than the whereby a somewhat viscous solution containing method used heretofore. the fibres in suspension is produced. For exr Previously in the method of covering wires with a p e, t e So u on ay Co sist o pu p 5 cotton or paper, acotton thread or paper tape fibre, 0. u us and Wate A W re is was wound ou d the wire throughout its entire passed through said solution while being revolved length. In order to obtain a uniformly covered so that the fibre in suspension in said solution is wire the cotton threads employed were very fine wound around the wire. Instead of revolving the l and the paper tapes employed were uniformly Wire, the solution in the vessel may be whirled 19 thin, so that it was comparatively expensive to around the wire by any suitable means with the cover the wire with a cotton thread or a paper me e e Sp e w th w ich the Wire is tape.
